TL;DR
Across all four measures, neural individuality was strongest in cortical areas showing greater evolutionary novelty in humans, particularly frontoparietal control and default mode networks, and weaker in more conserved primary regions.
Understanding the evolutionary origins of the structural substrates underlying self-processing is central to elucidating the neural basis of human cognition. Although self-related behaviors differ markedly across primates, the extent to which the underlying neural architecture is conserved or reorganized remains unclea...
Mammalian brains exhibit extensive diversity in size, cellular composition, and organization, yet the molecular evolutionary changes associated with this phenotypic diversification remain incompletely understood. Here, we investigated whether protein-sequence evolution covaries with quantitative differences in brain ph...
Comparing brain responses across species is essential for identifying models of human cognition and testing theories of brain evolution, but differences in brain size, measurement techniques, and signal dynamics make it challenging. Here we collected dense fMRI data in macaques and humans using the same movies, static-...
The article collection 'How Primates Became the Brainiest of All Mammals: A Closer Look at the Evolution of the Primate and Human Cortex' presents a wide-ranging analysis of encephalization across primates and humans. The papers in the collection tackle multiple classic themes in primatology, from brain ontogeny and re...
Abstract The human brain is organized by large-scale functional gradients, but whether white-matter connectivity defines similarly reproducible and biologically interpretable axes of cortical, subcortical, and cerebellar organization remains unclear. Here, we introduce Structural Connectivity Gradient Mapping (SCGM), a...
How differences in brain cell composition help define cortical folds are uncovered and a link between microscopic cellular organization and large-scale brain networks in primates is revealed.
